JAR-oLosURE.

SPECIFICATION brrning part `of Letters Patent No. 702,412, dated J une 17, 1902..

y Application .led November 27, 190i. Serial No. 83,862. {No.mudehl T @ZZ 1071/0711/ t may concerm Be it known that I, FRANK'E.- DoPnE'IDE, a citizen of the United States, residing at Palmyra,`in the county of Macoupin and State of Illinois, have invented anew and useful Jar- Closure, of whichthe following is aV specification.`

This invention relates to jarclosures5 and' itsobject is to facilitate the application'and removal of the closure-plug, todispense with external fastenings, so that the jar may be free from projections and obstructions, and at the same time to insure air-tight closing of the jar, so as to prevent ingress of dust and other foreign matter and also to prevent displacement of the plug by rough handling and by the pressure of the gases Within the jar. It is furthermore designed to so combine the neck of the jar, the closureplug,`and1 the packing-ring that the latter will be gripped .between the neck and the plug,` so as to effectually seal the jar and also to prevent withdrawal of the plug except under excessive pressure, which may be obtained`` by forcing some instrument under the iiange of-the plug and then prying the same out ofthe 'neck of the jar. i

With these and other objects in view the present invention consists in the combination and arrangement of parts, as will be herein-l after more fully described, shown in the accompanyin g drawings,`and particularly pointed out in the appended claims, it being un-k derstood that changes in the form, proportion, size, and minor details may be made .within the scope of the claims without *departing from the spirit or sacrificing anyof `Jthe ady sure-plug.

, vantages of the invention. -i

Referring to the accompanying drawings, 1`

designatesthe neckportion of'I any ordinary fruit-jar, which-isprovided with an inner marginalgroove 2, the upper wall of which is terminated short of the outer end of the lowerwall, so as to form a flange 3, which overhangs the rear portion only of the broad ledgeformed by the bottom of the groove.

" An ordinary thin flat rubber packingring 4,

as now commonly employed in connection with fruit-jars, and of greater width than the depth of the groove,` isplaced in the neck of the jar and rests against the ledge 5 or loottom of the groove 2, and in view of the comparative shortness of the upper flan ge 3 of the groove the packing-ring is `con veniently fitted in place, and-its outer edgereadilyvsnaps beneatli the overhanging flange 3, while'the inner edge'of the packing-ring inclin'esinwardly anddownwardly beyond-*thei'outer edge of the lower ledge or `bottom of the groove. The plug consists mof-a'circular body 6 of a diameter to bereadily inserted inthe outer end portion of the neck andtob'ind against the inner edge of the packingllring. The outer end or top of the plug is `.provided with an outwardly-directed marginalfange 7 to rest upon the upper edge of thejar; and thereby limit the inward` movement of the plug.

Another and much smaller annular enlarge-- i ment or ange 8 is formed upon the body of the plug and at the inner edge of the cap- Ilan ge 7. It will be i noted that the outer margin of the plug is curved inwardly from the lower edge oftheiiange or enlargement 8, as indicated at`9, and the lower marginal edge rof the plug is rounded or beveled inwardly,

as at `10, so as to slightly taper or reduce the lower end of `the plug to permit of said lower end of the plug sliding over the packing-ring and to prevent hanging of the plug upon the ring, as would be the case if the side and end walls of the plug met at right angles. When the plug isbeing inserted intoitheneck, it will be understood that the packing-ring is drawn downwardly and i partially out of the groove or seat 2 and isalso snugly wedged between the outer loweredge of the groove ICO or seat and the lower concaved portion of the flange or enlargement S of the plug, thereby preventing entire displacement of the packing-ring from its groove or scat. The fric-V to overcome the frictional engagement between the plug and the jar.

It is here desired to call 'attention to Fig. lof the drawings, wherein the plug has been shown slightly started from its closed position lwhereby the packing-ring is also forced outwardly, and in view of the fact that its outer edge is bent over the lower edge of its seat it will be forced outwardly and beneath the upper overhanging ilange 3 of the seat instead of being forced out of the neck of the jar with the plug. When `the outer edge of the packing-ring has come into engagement with the back of the groove and cannot be further displaced, its inner edge portionrucks up between the neck of the jar and the closure-plug, as the packing-ring is greater in width than the depth ofthe groove, which results in increased frictional engagement between the jar and the plug, and unless the force is sufficient to overcome this frictional engagement the closure-plug will not be displaced. Ordinarily rough handling and the pressure of the gases within fruit and pickle jars is not sufficient to force the plug out of the neck of the jar, and therefore' the present arrangement of parts, although extremely simple, is effective for the purpose designed and accomplishes the result of holding the closure-plug snugly.

within the neck of the jar without the employment of external fastenings.

I also contemplate sealing the jar by means of a piece of -paper or label ll, which is applied across the outer end of the plug and pasted to the upper edge of the jar, whereby dust is excluded from the joint between the plug and the jar, and it is necessary to destroy the paper seal or label when an implement is inserted between the cap-flange and the jar to pry the plug out of the neck of the jar. L y

After the closure-plug has been removed from the neck of the'jar the packing-ring may be removed from its seat in the neck and fitted to the closure-plug so as to snugly embrace the shouldered portion 8 thereof, so that when the plug is again inserted into the neck the packing-ring will bind upon the upper edge of the neck portion 8, so as to close the joint between the plug and the neck in a manner to exclude dust and foreign matter from the interior of the jar, whereby it will be understood that it is not necessary to again insert the plug to the original extent,`and the plug may be conveniently removed whenever it is desired to remove some of the contents of the jar withoutv requiring the application of force, as is necessary to unseat the plug from its original position.

What I claim isl. The combination with a jar having an inner marginal groove or seat formed in the neck thereof and provided with back, top and bottom walls and open at its front only, of a thin flat packing-ring of greater width than the depth of the groove with its outer edge seated in the groove and its inner edge projected out of and beyond the open' front of the groove or seat, and a closure-plug slightly less ,in diameter than the inner diameter of the neck of the jar at the lower side of the groove therein, and provided with an intermediate marginal enlargement or flange to bind the packing-ring between thelowerouter edge of the groove or seat and the lower edge of the iiange, whereby the packing-ring will be rucked up in the seat'upon an initial outward movement of the closure-plug and thereby prevent accidental displacement thereof.

2. The combination with a jar having an inner marginal groove or seat formed inthe neck thereof, a thin dat packing-ring having its outer edge seated in the groove and its inner edge projected inwardly and downwardly into the neck of the jar, and a closure-plug having its outer end provided with a marginal cap-flange t-o engage the upper edge of the jar, and an intermediate marginal ange or enlargement to engage the inner projected edge of the packing-ring and bind the same between the lower edge of the iiange and the lower outer edge of the groove or seat in the jar.

3. The combination with a jar, having an inner marginal groove or seat formed in the neck thereof, with the lower side of the groove projected into the neck-opening beyond the upper side thereof, a packing-ring of greater width than the depth of the groove with its outer edge fitted in the groove or seat and its inner edge projected out of the groove,- and a closure-plugI having a diameter slightly less than that lof the neck at the lower side of the groove therein, and also provided with an intermediate marginal enlargement or ange to bind the packing-ring between the lower edge of the groove or seat and the lower side of the ange, whereby the packing-ring will be rucked up in the seat upon an initial outward movement of the closure-plug and thereby prevent accidental displacement thereof.

4. 'The combination with a jar having an inner marginal groove or seatl formed in the neck thereof, the lower side of the groove being projectedyinto the neck and beyond the upper side of the groove, a thin fiat packingring having its outer edge tted in the groove and its inner edge projected out of the groove, and a closure-plug of slightly less diameter than the inner diameter of the neck at the lower side of the groove, and provided with an intermediate marginal enlargement or flange having a beveled lower side to bind the packing-ring between said lower side and the lower edge of the groove or seat, and an outwardly-directed marginal cap-fiange at IOO IIO

the outer end of the plug to overlap the upper edge of the jar.

5. The combination with a` jar having an inner marginal groove or seat formed in the neck thereof and provided with back, top

and bottom walls, and an open front, of a fiat packing-ring -of greater width-than the depth of the groove, withits outer edge seated in the groove and having its inner edge projected out of and beyond the open front of the groove or seat, and a closure-plug slightly less in diameter than the neck of the jar at the lower side of the groove therein and capable of frictional engagement with the projected inner edge of the packing-ring to bind the latter between the lower edge of the groove or seat: and the plug, whereby the packing-ringwill be rucked up in the seat upon aninitial outward movement of the closure-plug and thereby prevent accidental displacement thereof.
